1 · What the graph read from it

What it found

Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.

The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

2 · The registry

The trial behind it

Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.

Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract

objectivesBone marrow edema is a universal manifestation of rheumatoid arthritis (RA), and its pathological essence is a bone marrow lesion (BML) formed by various bone marrow (BM) immune cells. Neutrophils play an important role in inflammatory arthritis, but the role and mechanism of neutrophils in BML are not clear. MATERIALS AND

methodsGranulocyte colony-stimulating factor (G-CSF) -/- mice and wild type (WT) C57BL/6 mice were immunized for collagen-induced arthritis (CIA). Histological scores of arthritis were evaluated. Immunohistochemistry staining with anti-Ly6G was conducted. Neutrophil extracellular traps (NETs) in joint sections were determined by immunofluorescence staining. BM neutrophils were isolated for flow cytometry and NETosis induction in vitro.

resultsHistological study showed significant neutrophil infiltrations in BML of CIA mice. Inhibition of BM neutrophil production by G-CSF knock out can obstruct the induction of BML and CIA. In addition to abundant infiltrated NETs intra-articular, remarkable NETosis primed BM neutrophils were infiltrated in BML of CIA mice, which was positively related to bone erosion. Neutrophils derived from G-CSF-/- mice have diminished ability of NETs formation in vitro, while G-CSF induction can enhance its capacity of NETs formation.

conclusionsWe propose for the first time that the overproduced BM neutrophils in CIA mice are primed for NETosis in a G-CSF dependent manner, and these pathogenic cells may have an important role in inflammatory arthritis. Blocking this pathological process could be a potential strategy for the treatment of RA.
